What happens in the process of fossilization? When an animal dies and is buried, minerals from the sediment in which it lies replaces the organic material in bone, particle by particle.
2.
What are the three main areas of investigation (categories of evidence) accompanying a new fossil find? The fossil, the paleoenvironment, and the taphonomy.
3.
Name at least two things studying fossil remains can tell you. The sex and locomotor behavior.
4.
What are at least two aspects to investigate about a paleoenvironment where a fossil is found? The proximity to a water source, and climate.
5.
What is taphonomy?
The study of processes that occurred from death to discovery.
6.
What are the seven epochs of the Cenozoic era, in order from the most recent to the oldest?
a.
Holocene
b.
Pleistocene
c.
Pliocene
d.
Miocene
e.
Oligocene
f.
Eocene
g.
Paleocene
7.
What are the two main categories of dating technique, and one example of each? Relative dating and absolute dating. In relative dating life forms are compared to strata. In absolute dating they determine the age by the amount of parent and daughter atoms that are in the sediment around the fossil.
8.
Upon what main principle is relative dating based? It's based on stratigraphy.
9.
The decay rate of atoms, or the time it takes for one-half of the parent atoms to decay to form the daughter atoms is the radiometric dating.
10.
Name two important things that are influenced by plate tectonics. The geographical distribution patterns of all living things and the paleoclimate.
11.
What was the primary climatic change during the Cenozoic era? Cooling and drying.
12.
What are three main ideas that have been proposed to explain the adaptations of the earliest primates? Arboreal theory, predation theory, and primate/angiosperm coevolution.
13.
List four features of Plesiadapiformes (the earliest possible primates). Petrosal bulla, more rounded molar cups, arboreal features of the postcranial skeleton, and small brain size.
